I'm trying to create a model of an underground home using revit, and want to use the Roof From Face method of turning my domes into roofs. I originally had a component created for the domes, but I created a mass of the interconnecting shapes to use for this instead.When I try to pick the faces in the Roof From Face command, it only lets me pick one of the dome areas (the largest one) and the face of the others that would lay on the foundation wall. It doesn't register any of the other dome areas as being faces. They were all created the same way in the same mass.I'm using Revit 2014. Here is an image of the dome structure. I'm putting in a dropbox link to the rvt file as well: https://dl.dropboxusercontent.com/u/1603555/FinalProjectDome.rvt
